Catalytic Activity of Multi-metallic Perovskite-Type Oxide Prepared by the Thermal Decomposition of Heteronuclear Cyano Complex, Sm[Fe x Co1-x (CN)6] •A nH2O

The perovskite-type SmFe (x) Co1-x O-3 oxides were prepared by the thermal decomposition of heteronuclear cyano complexes, Sm[Fe (x) Co1-x (CN)(6)] a (TM) nH(2)O. XRD studies demonstrated that SmFe (x) Co1-x O-3 catalyst prepared by the thermal decomposition of heteronuclear cyano complex at 1,273 K showed orthorhombic structure in whole range of x. The catalytic activity for CO oxidation was dependent on x in SmFe (x) Co1-x O-3; the maximum activity was obtained for SmFe0.5Co0.5O3.
